#AMD 6800XT SOFTWARE#
AMD’s Radeon Software comes also with several presets, including the much anticipated Rage Mode (which raises the power limits on the card), and an automatic overclocking option that removes the legwork from figuring out a stable, notched up frequency. The Radeon 6800 XT offers a “Game Clock” of 2015 MHz and a Boost Clock of up to 2250 MHz. The guaranteed clock speeds are impressive, though as we’ve seen with cards for a number of years, they really only hint at what the cards may achieve. In real world terms, I wasn’t able to notice any difference while gaming, but it’s worth being aware as game engine development continues to advance. In other words, this Navi GPU has faster memory than you might expect from GDDR6, but it still doesn’t compare well to the G6X in the RTX 3080.
There, the 6800 XT is substantially faster than the RTX 3070’s 448 GB/s. If we go down a step to the RTX 3070, we find a much more “apples to apples” comparison since it is also running GDDR6 on a 256-bit bus. The RTX 3080 uses the cutting edge GDDR6X and offers a maximum memory bandwidth of 760 GB/s.
If you recall from my review of the RTX 3080 Founders Edition, the RX 6800 XT’s main competitor, this memory configuration isn’t as fast. It marries that with 16GB of GDDR6 memory (topping all but the RTX 3090 from Team Green) on a 256-bit bus bearing a total bandwidth of 512 GB/s. Likewise, it features 72 Compute Units, up from 40 last-gen, and each has its hardware level ray tracing unit (which we’ll get to shortly). Last generation’s 5700 XT featured 2560 SPs, while the 6800 XT bumps that all the way to 4608. With that, the GPU has received a massive expansion in Stream Processors, which are responsible for game rendering. Like the RX 5700 XT, it uses AMD’s 7nm process, but the transistor count has more than doubled, going from 10.3 billion to 26.8 billion. The RX 6800 XT is built on AMD’s RDNA 2 architecture. What really matters is what that heatsink is keeping cool.
